Roller wheels 1 1/4 . mounting hole to mounting hole centers 5 3/4 . total length 6 1/4 . Stainless preferred but will take steel if all you have . I will need two assemblies.

Thanks for reaching out to us. Your roller looks like a match for our 81-018, though perhaps an older version of it. Look our product over and let me know what you tihnk.
